The performance and safety of the radioisotope power source depend in part on the thermal and impact properties of the materials used in the general purpose heat source (GPHS) through the use of an impact shell, thermal insulation and an aeroshell. Results from an earlier study indicate the importance of circumferential fibers to the mechanical properties of cylindrical filament wound carbon-carbon composites for the impact shell application. Based on this study, an investigation was initiated to determine the processing characteristics and the mechanical and thermal response of three filament wound configurations with different percentages of circumferential fibers: 50%, 66% and 80%. The performs were fabricated using a 3-D filament winding machine followed by five cycles of resin impregnation and carbonization. In this paper, the processing sequence and the resulting microstructures of the composites will be described. The thermal conductivity values of the composites as a function of fiber configuration and density will be discussed. These results will be compared with the fine-weave pierced-fabric (FWPF) material and carbon-bonded carbon-fiber insulation. Finally, the relevance of the new configurations for applications in the general purpose heat source (GPHS) will also be inferred.
